The purpose of this study was to examine the extent to which self-regulated study strategies and predictor variables predict performance success in instrumental performance college courses. Preservice music teachers (N=123) from a music education department in two state universities in Turkey completed the Music Self-Regulated Studying Strategies Survey (MSRSSS) developed from theoretical models of self-regulation in music. The MSRSSS displayed a three-factor solution that included strategies related to planning, monitoring, and evaluation stages of study. An examination of psychometric properties revealed evidence for scale reliability and validity. Multiple regression analyses indicated that monitoring but not planning was a statistically significant predictor of performance success in instrumental performance courses over and above the effects of Grade Point Average (GPA). Evaluation strategies were also significant in predicting performance success in instrumental courses but with an inverse relationship. Besides, academic success in theoretical courses as a predictor variable was the strongest predictor of performance success in instrumental courses. Findings and implications for music education are discussed.
